[0016] This application provides a mobile microwave heating box for asphalt mixtures, such as... Figure 1 As shown, the mobile microwave heating box for asphalt mixture includes a chassis 100, a microwave heating device 200, and a conveying device 300. The microwave heating device 200 is mounted on the chassis 100. One end of the conveying device 300 is located above the microwave heating device 200, and the other end of the conveying device 300 is used to receive the asphalt mixture to be heated. The conveying device 300 is configured to convey the asphalt mixture to the microwave heating device 200.

[0017] The mobile asphalt mixture microwave heating box can be towed by a vehicle and quickly reach the construction site. The conveying device 300 is used to transport the asphalt mixture that needs to be heated to the microwave heating device 200. The microwave heating device 200 sends microwaves to the asphalt mixture, so that the inside and outside of the asphalt mixture are heated simultaneously, and then discharged from the microwave heating device 200.

[0018] Continue to refer to Figure 1In some embodiments of this application, the conveying device 300 includes a first funnel 310, a first scraper conveyor 320, and a first belt conveyor 330; the first scraper conveyor 320 is installed at the bottom of the first funnel 310; one end of the first belt conveyor 330 is located below the first scraper conveyor 320, and the other end of the first belt conveyor 330 is located above the microwave heating device 200.

[0019] When the conveying device 300 is working, the asphalt mixture that needs to be heated is put into the first funnel 310, and the asphalt mixture falls from the bottom of the first funnel 310 to the first scraper conveyor 320; the first scraper conveyor 320 removes the asphalt mixture, and the asphalt mixture falls from one end of the first scraper conveyor 320 and lands on the first belt conveyor 330; the first belt conveyor 330 conveys the asphalt mixture to the top of the microwave heating device 200, and after falling from the first belt conveyor 330, the asphalt mixture enters the microwave heating device 200.

[0020] The conveying device 300 conveys asphalt mixture to the microwave heating device 200 through a multi-stage relay method consisting of a first funnel 310, a first scraper conveyor 320, and a first belt conveyor 330.

[0021] In some other embodiments of this application, the conveying device 300 includes a first belt conveyor 330, one end of which is located above the microwave heating device 200. When the conveying device 300 is working, the asphalt mixture to be heated is placed directly on the first belt conveyor 330. The first belt conveyor 330 conveys the asphalt mixture to the top of the microwave heating device 200, and the asphalt mixture falls from the first belt conveyor 330 and enters the microwave heating device 200.

[0022] like Figure 2 As shown, in some embodiments of this application, the microwave heating device 200 includes a housing 210, a second funnel 220, a microwave heating chamber 230, a second scraper conveyor 240, and a second belt conveyor 250; the top of the housing 210 has a feed inlet, the second funnel 220 is located inside the housing 210, and the top of the second funnel 220 is connected to the edge of the feed inlet; the microwave heating chamber 230 is installed inside the housing 210; the second scraper conveyor 240 is installed inside the housing 210, and one end of the second scraper conveyor 240 is located below the outlet of the second funnel 220, and the other end of the second scraper conveyor 240 is located inside the microwave heating chamber 230; the housing 210 has an outlet, the second belt conveyor 250 is installed inside the housing 210, and one end of the second belt conveyor 250 is located at the outlet of the microwave heating chamber 230, and the other end of the second belt conveyor 250 is close to the outlet.

[0023] The asphalt mixture enters the second funnel 220 from the inlet of the shell 210 and falls from the bottom of the second funnel 220 to the second scraper conveyor 240. The second scraper conveyor 240 conveys the asphalt mixture to the microwave heating box 230. The microwave heating box 230 heats the asphalt mixture, and the heated asphalt mixture falls from the outlet of the microwave heating box 230 to the second belt conveyor 250. The second belt conveyor 250 conveys the asphalt mixture to the outlet of the shell 210.

[0024] The microwave heating box 230 can send microwaves to the asphalt mixture, thereby heating the inside and outside of the asphalt mixture simultaneously. Compared with traditional electric heating wire heating, microwave heating is faster and consumes less energy. After the asphalt mixture is reheated by the microwave heating box 230, it can be reused, allowing the recycled asphalt to be spread evenly and ensuring compaction, thus improving the smoothness and durability of the road surface.

[0025] like Figure 1 As shown, in some embodiments of this application, the mobile asphalt mixture microwave heating box further includes a lifting device 400, which is installed on the chassis vehicle 100, and the microwave heating device 200 is installed on the top of the lifting device 400.

[0026] The lifting device 400 can raise and lower the microwave heating device 200, so that the overall height of the mobile asphalt mixture microwave heating box can be reduced during transportation, making it easier to pass through height-restricted locations.

[0027] Continue to refer to Figure 1 The mobile microwave heating box for asphalt mixture also includes a discharge device 500, one end of which is located below the discharge port of the microwave heating device 200. The recycled asphalt flowing out of the discharge port of the microwave heating device 200 falls onto the discharge device 500, which then outputs the recycled asphalt to an asphalt transport vehicle.

[0028] Specifically, the discharge device 500 includes a fourth belt conveyor, one end of which is located below the discharge port of the microwave heating device 200.

[0029] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0030] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
